Definitions

  • the invention relates to a plain bearing with a support shell and a roll-clad running layer made of an aluminum alloy with dispersed, soft inclusions.
  • running layers made of an aluminum alloy with dispersed, soft deposits do not adhere sufficiently to a steel support shell during roll cladding
  • the running layer is first connected to a film made of technically pure aluminum by a rolling process before this layer composite is plated onto the support shell.
  • the intermediate layer made of aluminum foil ensures a sufficient adhesion promoter, but the fatigue strength of such roll-clad bearings remains comparatively low, on the one hand because of the material properties of the aluminum intermediate layer and on the other hand due to the required thickness of the running layer, which must ensure a predetermined wear reserve because the aluminum intermediate layer does not has emergency running properties.
  • the invention is therefore based on the object of designing a plain bearing of the type described in such a way that the fatigue strength can be increased considerably.
  • the invention achieves the object in that the running layer is applied to a layer made of a hardenable aluminum alloy.
  • hardenable aluminum alloys are harder than mixed-crystal hardened aluminum alloys even in the soft-annealed condition, such hardenable aluminum alloys can surprisingly be roll-plated with aluminum-based overlay without fear of a reduction in the adhesion of the overlay to the support shell.
  • the reason for this is probably to be found in the fact that the hardenable aluminum alloys are subject to considerably less embrittlement and hardening during cold forming, so that cracking can be largely ruled out.
  • Foils made of hardenable aluminum alloys are therefore suitable as adhesion promoters between aluminum-based running layers and steel support shells, whereby the advantage of a noticeable increase in the fatigue strength of these plain bearings is achieved.
  • this running layer for example an AlSn20 layer
  • this running layer is first coated with a pure aluminum foil 4 according to the prior art according to FIG. 1 Roll plating connected before this layer composite is plated onto the steel support shell 3. Since this pure aluminum foil has a hardness of approximately 28 HV 0.5 compared to a hardness of approximately 35 to 40 HV 0.5 of the running layer, the fatigue strength of such bearings naturally remains limited. especially since the running layer thickness must be greater than 0.3 mm to ensure a sufficient wear reserve.
  • the running layer 1 is connected to a hardenable aluminum alloy by roll cladding, which either forms an intermediate layer 5 between the running layer 1 and the steel support shell 3 according to FIG. 2 or the support shell 3 itself after hardening according to FIG. 3. That the fatigue strength of the slide bearing can be improved by a harder intermediate layer 5 is to be expected, but it is surprising for the person skilled in the art that the adhesion of the running layer to the support shell 3 is not impaired by a hardenable aluminum alloy, as is the case, for example, with intermediate layers non-hardenable aluminum alloys due to the formation of cracks, although these mixed crystal hardened aluminum alloys, e.g. B.
  • AlCu1Ni0.5 have a lower hardness than even soft-annealed hardenable aluminum alloys.
  • the hardenable aluminum alloys have emergency running properties, as is the case for. B. is given at AlZn4SiPb. Because of the emergency running properties of the hardenable aluminum alloys, the running layer 1 no longer needs to form the wear reserve, so that the running layer thickness can be reduced with a corresponding thickness of the intermediate layer 5.
  • a thickness of 0.4 mm was chosen for the intermediate layer 5 and a thickness of 0.2 mm for the overlay.
  • the hardness of the intermediate layer 5 can be specified for an AlZn4SiPb alloy with approximately 60 HV 0.5 and that of the overlay (AlSn20Cu) with approximately 35 to 40 HV 0.5.
  • the ever increasing hardness from the running layer 1 via the intermediate layer 5 to the support shell 3 has a favorable effect on the fatigue strength and thus on the load-bearing capacity and the service life of the plain bearing.
  • the hardenable aluminum alloy can also be hardened and then used as a support shell itself, which supports the running layer 1 without an intermediate layer.
  • the invention is of course not limited to the exemplary embodiments, so all suitable aluminum alloys with soft inclusions made of Sn, Pb or Bi could be used as the running layer.
  • AlZn4SiPb AlZn4.5Mg, AlSi11CuMgNi or AlMgSi1 are also particularly suitable as hardenable aluminum alloys for roll cladding with an aluminum-based overlay.
